Written by Rhett, Jesse Frasure, Ashley Gorley and Shane McAnally while on tour, "Unforgettable" is a mid-tempo love song. Lyrics include “I can smell your perfume / Girl, that night was just like you / Unforgettable" and "From your blue jeans to your shoes, girl, that night was just like you / Unforgettable."

“We kind of told the story of -- basically, it could be a boyfriend or it could be a husband, describing to his wife all these amazing details that she probably thought he’d forgotten about," Rhett says. To the Tennessean, he adds, "If you listen to it hardcore enough, it might make you tear up a little bit. Especially if you’re in love with somebody.”

"Unforgettable" gets bonus points for earning the approval of Rhett's wife Lauren, too. Readers can press play below to hear it, and see a lyric video for the track.
